What is an example of a theme related to identity?

The journey of self-discovery is a central theme related to identity because it directly involves the exploration and understanding of one’s own character, beliefs, values, and individual place in the world. This theme encapsulates the experiences, challenges, and revelations that shape a person's identity over time. It often involves characters grappling with who they are versus who society expects them to be, which can lead to significant personal growth and transformation.

In contrast, the other options, while they may contain important themes in literature, do not specifically focus on the concept of identity. The resolution of a family conflict primarily pertains to interpersonal relationships rather than an individual's self-concept. The rise and fall of empires deals more with historical events and societal structures rather than personal identity. The importance of friendship highlights social connections but does not delve into the challenges of self-discovery or personal identity formation.
